Study on driver-intent estimation at yellow traffic signal by using driving simulator

This paper proposes two methods based on vehicle behavior for predicting whether a driver approaching a signalized intersection decides to stop or pass through the intersection when the signal turns from yellow from green. The first method predicts whether a driver decides to stop when the signal turns yellow, based on the idea that whether a driver decides to stop should depend on the situation and the vehicle behavior at the moment the signal turns yellow. The second method estimates whether a driver has decided to stop, in other words, whether the driver has the intent to stop, based on the idea that the driver´s intent will appear in the vehicle behavior when the driver has decided to stop or pass through the yellow signal; this method can also detect a change in the driver´s intent on the way to the intersection. The effectiveness of these two methods is demonstrated with experiments conducted in a driving simulator.
